During the Beiyang era, warlords fought one another while Chinese and foreign powers colluded, coveting China’s cultural treasures. As a result, countless historic sites were destroyed and countless artifacts ended up overseas.
To protect the nation’s treasures, Cao Nanwu, the last tomb guardian of the Cao family, steps forward. Together with Xia Kuxue, a feng shui servant; Shixiangsheng, a ghost servant; and Ami, a tomb-guarding beast, he pits his wits against the mysterious organizations Nightless Lamp, Hall of Immortality, and Black Cicada Society. They successfully foil the criminals’ schemes and preserve the nation’s cultural treasures.
